COMBINATION CHURN AND FREEZER.

Application filed March 24, 1924. SerialNo. 701,370.

To all whom it may concern:

Be it known thatI, lVARRnN S. GAUN'rr, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Combination Churns and Freezers, of which the following is a specification.

My invention relates to a combination churn and ice-cream freezer and one object is to provide a new and useful apparatus of this character having vibratory supporting means requiring but minimum effort and time in its operation.

A further object is the provision of an agitator for use in the churn to brealz up the butter globules during the churning opera-- tion.

Another object is the provision of a lid for centralizing an inner container within an outer container of the apparatus during the process of producing ice-cream.

Other objects will hereinafter appear, and in order that the invention may be fully understood, reference will now be had to the accompanying drawing, in which:

Fig. 1 is a side elevation, partly in section of the apparatus.

Fig. 2 is an irregular horizontal section taken on line llI-II of Fig. 1.

Fig. 3 .is a planview of the outer container, 'the agitator arranged therein, and the immediate support for said outer container. I

Fig. {i is a detail perspective view of the inner container.

Referring now in detail. to the various parts, 2 designates an outer container made,

preferably, of sheet metal. and provided with a handle 4, an upper outlet 6. and a lower outlet 8.

10 designates the inner container also, preferably made of sheet metal and removably arranged within the outer container 2.

12 designates a lid for covering the months at the upper ends of the containers 2 and 10. Said lid ,12 has a depending marginal flange 14 to snugly fit over the upper end of the outer container 2 and has a central circular depression 16 which snugly fits within the upper end of the inner contai er 10 to hold the same centrally within said outer container 2 as shown by Fig. 1. An annular rubber or other suitable gasket 18, secured inside the lid 12 between its marginal flange 14 and depression 16, is provided to obtain an air-tight joint between the lid 12 and the upper ends of the outer and inner containers 2 and 10, respectively.

The outer container 2 is provided near its upper end with interior supporting elements 20 which are, preferably, equally ported by a lower transverse bar 30, which in turn is st -)ported by a U-frame 32 formed, preferably, from a single rod threaded at its ends to receive thumb-nuts 34. The U- frame 32 is supported by an upper trans- Verse bar 36, which fits loosely over the I threaded ends thereof and is clamped firmly down upon the lid 12 by the thumbnuts 34:.

The upperend of the transverse bar 36 is proirided with a centrally-disposed eye 48 in which the lower end of a coil. spring 50 is engaged, the upper end of said spring engaging in a supporting member 52 which may be fixed to a vertical wall or other supportA. The iliframe 32 is provided with a central bent portion 54 to receive the upper end of a coil spring 56 arranged in al inement with the spring 50 and connected at its lower end to a hook 58, which may be screwed into the floor B.

In practice when butter is to be produced the inner container 10 is removed and the agitator. 22 is placed in position upon the supporting elements 20. Stoppers 59 and (50 are placed in the outlets 6 and 8, respectively, after which cream is placed in the container 2, upon which the lid 12 is then placed. The container 2 is then placed upon the lower transverse bar 30, after which the uppertransverse bar 35 is placed over the upper ends of the U-frame 32 and down upon the lid 12 where it is firmly held on downward adjustment of the nuts 8%. The

container 52 is then suddenly forced downwardly to distend the spring 50, which. upon rebounding. will distend the spring 56. Sudden alternate distension of the springs 50 and 56 imparts a rapid. vibratory motion to the churn which in turn agitates the cream and rapidly produces l. utter, the globules being broken up by violent contact with the agitator 22. After the churning operation has proceeded sufficiently to cause gases to form the stopper 59 is removed for a short time to permitsaid gases to escape.

\Vhen ice-crearn is to be produced the inner container 10 is substituted for the agitator 22. Cream and its flavoring, extracts are then placed within said container 10, while cracked ice is packed. in the annular chamber 56 oetwcen the cylindrical Walls of the outer and inner containers 2 and 10, respectively. While the cracked ice is being placed, the inner container 10 is held centrally Within the outer container 2 by a stud 62, which projects upwardly from. the bottom of the latter into a protuberance 64 in the bottom of the former. The lid 12 is then placed in position to cover the mouths of the inner and miter containers and to react with the stud 2 and the protuberance in firmly holding the inner container l0 centrally within the outer container The containers are then vibrated to hasten the freezing operation, which is accelerated by the cold air, confined by the lid 12 and gasket 18, being forced around menace out, and while I have shown and described the preferred construction, combination and arrangement of parts, I reserve the right to make such changes as properly fall with in the spirit and scope of the invention as claimed.

Havirw thus described my invention, what I claim and desire to secure by Letters Patent. is:

An apparatus of the character described consisting of a container, a lid thereto, supporting elements spaced about in the in terior of said container, and an agitator mounted on said sup 'iorting elements and consisting of spring wire formed intoian expansible split-ring for frictional engagement with the interior of said container and provided with interior coils, for the purpose described.

in testimony whereof I ailix my signature, in the presence of two Witnesses.
